A method of processing state information in a radio access network (100). The radio access network (100) includes a first radio access node (103, 104) that is associated with a cell (105, 106) and user equipment (102). The method comprises maintaining state information at the user equipment (102), the state information comprising at least one state information part associable with different values. The method further comprises transmitting a current value associated with at least one state information part from the user equipment (102) to the first radio access node (103, 104) in response to detecting at least one predetermined trigger indicating that the first radio access node (103, 104) may not hold the current value. The method further comprises relying on the first radio access node (103, 104) holding the current value associated with the at least one state information part if no predetermined trigger is detected.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method by a terminal in a radio access network, the method comprising: receiving, from a base station, a first control message including information on one or more frequencies for measurement; identifying whether an in device co-existence (IDC) interference is detected on a first set of at least one frequency among the one or more frequencies; if the IDC interference is detected on the first set of the at least one frequency, transmitting, to the base station, a second control message including information associated with the first set of the at least one frequency; and if the IDC interference is no longer detected on the first set of the at least one frequency, transmitting, to the base station, a third control message, wherein the third control message does not include the information associated with the first set of the at least one frequency.
2. The method of claim 1 , wherein the IDC interference is detected on at least one frequency among the one or more frequencies when the terminal is configured to transmit an IDC indication.
3. The method of claim 1 , wherein the first control message includes a radio resource control (RRC) message.
4. The method of claim 1 , further comprising: identifying that the IDC interference is detected on a second set of at least one frequency among the one or more frequencies; if the IDC interference is detected on the second set of the at least one frequency, identifying whether the second set is different from the first set; and if the second set is different from the first set, transmitting, to the base station, a fourth control message for the second set of the at least one frequency, wherein the fourth control message includes information associated with the second set of the at least one frequency.
5. A method by a base station in a radio access network, the method comprising: transmitting, to a terminal, a first control message including information on one or more frequencies for measurement; receiving, from a terminal, a second control message for a first set of at least one frequency among the one or more frequencies if an in device co-existence (IDC) interference is detected on the first set of the at least one frequency, wherein the second control message includes information associated with the first set of the at least one frequency; and receiving, from the terminal, a third control message if the IDC interference is no longer detected on the first set of the at least one frequency, wherein the third control message does not include the information associated with the first set of the at least one frequency.
6. The method of claim 5 , wherein the IDC interference is detected on at least one frequency among the one or more frequencies when the terminal is configured to transmit an IDC indication.
7. The method of claim 5 , wherein the first control message includes a radio resource control (RRC) message.
8. The method of claim 5 , further comprising: receiving, from the terminal, a fourth control message for a second set of at least one frequency among the one or more frequencies if the IDC interference is detected on the second set of the at least one frequency which is different from the first set of the at least one frequency, wherein the fourth control message includes information associated with the second set of the at least one frequency.
9. A terminal in a radio access network, comprising: a transceiver; and at least one processor coupled with the transceiver and configured to control to: receive, from a base station, a first control message including information on one or more frequencies for measurement, identify whether an in device co-existence (IDC) interference is detected on a first set of at least one frequency among the one or more frequencies, if the IDC interference is detected on the first set of the at least one frequency, transmit, to the base station, a second control message including information associated with the first set of the at least one frequency, and if the IDC interference is no longer detected on the at least one frequency, transmit, to the base station, a third control message, wherein the third control message does not include the information associated with the first set of the at least one frequency.
10. The terminal of claim 9 , wherein the IDC interference is detected on at least one frequency among the one or more frequencies when the terminal is configured to transmit an IDC indication.
11. The terminal of claim 9 , wherein the first control message includes a radio resource control (RRC) message.
12. The terminal of claim 9 , wherein the at least one processor is further configured to control to: identify that the IDC interference is detected on a second set of at least one frequency among the one or more frequencies, if the IDC interference is detected on the second set of the at least one frequency, identify whether the second set is different from the first set, and if the second set is different from the first set, transmit, to the base station, a fourth control message for the second set of the at least one frequency, wherein the fourth control message includes information associated with the second set of the at least one frequency.
13. A base station in a radio access network, comprising: a transceiver; and at least one processor coupled with the transceiver and configured to control to: transmit, to a terminal, a first control message including information on one or more frequencies for measurement, receive, from a terminal, a second control message for at least one frequency among the one or more frequencies if an in device co-existence (IDC) interference is detected on the first set of the at least one frequency, wherein the second control message includes information associated with the first set of the at least one frequency, and receive, from the terminal, a third control message if the IDC interference is no longer detected on the first set of the at least one frequency, wherein the third control message does not include the information associated with the first set of the at least one frequency.
14. The base station of claim 13 , wherein the IDC interference is detected on at least one frequency among the one or more frequencies when the terminal is configured to transmit an IDC indication.
15. The base station of claim 13 , wherein the first control message includes a radio resource control (RRC) message.
16. The base station of claim 13 , wherein the at least one processor is further configured to control to: receive, from the terminal, a fourth control message for a second set of at least one frequency among the one or more frequencies if the IDC interference is detected on the second set of the at least one frequency which is different from the first set of the at least one frequency, wherein the fourth control message includes information associated with the second set of the at least one frequency.
